Description
VNBに由来するみかけのヨウ素価=〔VNBのビニル基に由来するピークの積分値〕/〔ENBに由来するピークの積分値〕×〔 13 C−NMRスペクトルメーターより求めたENBの重量%〕×253.81/120.2
〔共重合体(A)の製造方法〕
本発明に用いる共重合体(A)は、メタロセン触媒を用いて合成される共重合体であることが好ましい。メタロセン触媒として、下記式(IA)、(IIA)または(III)で表わされる触媒が好ましい。
Apparent iodine value derived from VNB = [integral value of peak derived from vinyl group of VNB] / [integral value of peak derived from ENB] × [weight% of ENB determined from 13 C-NMR spectrometer] × 253.81 / 120.2
[Method for Producing Copolymer (A)]
The copolymer (A) used in the present invention is preferably a copolymer synthesized using a metallocene catalyst. As the metallocene catalyst, a catalyst represented by the following formula (IA), (IIA) or (II I) is preferable.
炭素数1〜20のヒドロカルビル基としてはメチル基、エチル基、ブチル基などの直鎖状アルキル基、t-ブチル基、ネオペンチル基などの分岐状アルキル基が挙げられ、ヒドロカルビルオキシ基としては、メチルオキシ基、エチルオキシ基、ブチルオキシ基などの直鎖状アルキルオキシ基、t-ブチルオキシ基、ネオペンチルオキシ基などの分岐状アルキルオキシ基が挙げられ、ハロゲン化アルキル基としては、前記の直鎖状アルキル基や分岐状アルキル基をクロル化、臭素化、フッ素化したものが挙げられる。またはハロゲン化アリール基として、クロル化フェニル基、クロル化ナフチル基などが挙げられる。
上記式(III')中、R''が水素原子またはメチルであるのが好ましく、メチルである場合が好ましい。
Examples of the hydrocarbyl group having 1 to 20 carbon atoms include linear alkyl groups such as a methyl group, an ethyl group and a butyl group, and branched alkyl groups such as a t-butyl group and a neopentyl group. Examples include linear alkyloxy groups such as oxy group, ethyloxy group, and butyloxy group, and branched alkyloxy groups such as t-butyloxy group and neopentyloxy group. And chlorinated, brominated or fluorinated groups or branched alkyl groups. Examples of the halogenated aryl group include a chlorinated phenyl group and a chlorinated naphthyl group.
In the above formula (III ′) , R ″ is preferably a hydrogen atom or methyl, and is preferably methyl.
